Answer:
a) P = 2/7
b) P = 4/7
c) P = 1/7
Step-by-step explanation:
In the range of [2,8], we have the following integers which are: 2, 3, 4, 5, 6, 7, 8. So this is a total of 7 integers.
a) We look for the probability that the numbers are less than 4, so we conclude that there are possible numbers 2 and 3 out of possible 7, so the required probability is equal to P = 2/7.
b) We look for the probability that the numbers are greater than 4, so we conclude that there are possible numbers 5, 6, 7, 8 out of possible 7, so the required probability is equal to P = 4/7.
c) Based on the previous two examples, we conclude that the required probability is P = 2/7· 1/2=1/7.
3 < k
Step-by-step explanation:
Simplify by undoing addition to both sides, then divide both sides by the coefficient of k.

Answer:
║JF║=75
Step-by-step explanation:
angle JDF = angle JYS ( corresponding angles)
angle JYD = angle JSF ( corresponding angles)
JD/JF=JY/JS=DY/FS
Use JD/JF=JY/JS and substitute:
50/x=42/63, where║JF║
cross multiply
50×63=42×X
3150=42x
divide via by 42
3150/42=42x/42
75=x
x=75
So ║JF║=75
Hope this helps.
